Consider the circuit shown in the figure. w R 90.0 Ω 10.0 Ω a b 10.0 Ω 90.0 Ω (a) Let the equivalent resistance of the circuit when the switch is open be Req, open' and the equivalent resistance when the switch is closed be Req, closed Find the difference (in (2) between the two equivalent resistances, Req, open - Req, closed" Req, open - Req, closed = Ω (b) When the switch S is closed, the equivalent resistance drops to 52.0% of the original value. Determine the value of R (in (2). Ω (c) What If? What would the voltage (in V) between points a and b have to be for 200 W to be delivered to the circuit when the switch is closed? Assume that R has the value found in part (b). V

Bidirectional counters, also known as Up/Down counters, are capable of counting in either direction through any given count sequence and they can be reversed at any point within their count sequence by using an additional control input as shown in Figure 2.1. Construct the truth table and decide the sequence of a 4-bit synchronous binary up/down counter for the given clock pulse and UP/DOWN control inputs given in Appendix 1. The counter is positive edge triggered and start with all LOW state.
